$220, that was a touch up on an existing tune.

Sweet. Now that I got my fueling and CAS fixed, I wanna get the Stagea on the rollers to get back those lost ponies.

Did a compression check a while ago and thankfully no compression loss or blown rings etc. Thankful that I babied the stag around when I knew it wasn't running right.

I wanna get to that turbo/dump gasket leak this weekend too.

damo that boost curve looks consistent with the r34 turbo

a really good ebc may fix up the peak & hold boost, or better yet a fully tuneable computer

as it is it isnt a bad tune...

i have a power fc, but a shit boost tee.

ah simple then, save for the power fc boost controller - scour ebay, JPS Trading Ltd is a good trader to search thru

you can see where the boost T isnt cutting the mustard from 80-120kmph

see how a decent boost controller works better ?

edit: the dropping off of boost was from restricted exhaust, much flatter now at the pointy end of the graph

tune of new piggyback ecu on 8th Oct, update then with a 250+ kw tune map

If you still have the factory boost solenoid in line then i expect if you had a your boost graphed then this is what it would look like (This is a mates figure from his 33). How much boost are you running? Is yours an auto or manual because that figure looks a bit low to me (depending on boost). The other thing that would be playing a part in the hole is the VTC timing not being perfect.

still dropping off - but fuelling is the issue here

again, on 8th oct bigger injectors slot in, so will update some graphs for discussion.

Id suggest damo that a better ebc will do the job well. p-fc boost controller.

Where is the dropping off boost shown?

The graph says 10-11psi, when he rang i said around 10.5psi would be fine, and i assume thats what its on, hard to read from factory bar guage. Its a manual.

Its a turbosmart bleed valve, and always has lost boost from 4000ish to redline since it was fitted.

:D This is gonna sound pretty gay. But for some reason Damo, You were in a dream of mine last night. And you drove a VT commodore.

Thats sweet Craig. and by "drove a VT Commodore" i hope you mean "watched you have sex with Megan Fox"

    • Neo IACVs have water plumbed into/out of them to provide the heat to close the AAC. I am also unsure about vanilla 25s, but maybe the extra plumbing on that is water.
    • Those injectors are 100% Nismo 555.
    • I found this in another thread, now I'm second guessing myself and thinking there was a vac line from near the throttle body to up to the IACV too.   https://saufiles.s3.ap-southeast-2.amazonaws.com/post-59171-1251456228_thumb.jpg
    • Hey Duncan,  What ports are on the plenum itself? The new part welded up for the AAC looks like it's a T Piece to go upto brake master, and the other side into the plenum to feed air in. Brake master vac line on R33 from memory has a one way valve inside of it I believe (middle of pipe). I'll check mine tonight when I get home, I think that pipe is still sitting on my R33. You're also testing my memory, but I don't believe the R33 has a cold start valve, it just has the IACV doesn't it? That second smaller port on the IACV itself from factory, goes down and under the inlet manifold, but I can't remember what it plumbs to.
    • I once hit my knee on an exhaust on my sisters Suzuki Sierra after she drove it her *normal* way. My knee looked like porridge for weeks. Bec and my daughters never go near this car. I can see one of my dogs losing an ear though. 🤔
